162711-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162711-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,7,1 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 162711-89:
(8*1)+(7*6)+(6*2)+(5*7)+(4*1)+(3*1)+(2*8)+(1*9)=129
129 % 10 = 9
So 162711-89-9 is a valid CAS Registry Number.
